Seeds of Centranthus ruber and Valeriana officinalis Contain Conjugated Linolenic Acids with Reported Antitumor Effects.

Conjugated linolenic acids (CLNs) are naturally occurring fatty acids that are believed to have anticancer properties. In this study, we examined various plant seeds from herbs to discover seed oils containing CLNs. The ultraviolet spectra of total lipids from these seeds were measured.

Monitoring of QoI fungicide resistance in Plasmopara viticola populations in Japan.

Background: The increasing occurrence of QoI fungicide resistance in Plasmopara viticola (Berk. & MA Curtis) Berl. & DeToni populations is becoming a serious problem in the control of grapevine downy mildew.

Characterization of thermotolerance-related genes in grapevine (Vitis vinifera).

We report the cloning and characterization of heat shock-induced genes in grapevine (Vitis vinifera L.). Using the cDNA subtraction method, four heat shock-induced genes were identified in heat shock-treated Pinot noir grapevine.

Rapid method for detecting resistance to a QoI fungicide in Plasmopara viticola populations.

Background: The increasing occurrence of Qo inhibitor (QoI)-fungicide-resistant Plasmopara viticola (Berk. & MA Curtis) Berl. & DeToni populations is becoming a serious problem in the control of grapevine downy mildew worldwide.

Cloning and characterization of VIGG, a novel virus-induced grapevine protein, correlated with fruit quality.

We report here the identification and characterization of VIGG, a novel virus-induced grapevine protein. Analysis of VIGG expression in grapevine demonstrated that VIGG was constitutively expressed in leaves and stems in virus-infected grapevine, and that VIGG expression was induced by grapevine virus A (GVA) infection, but not by infection with other viruses. The virus-induced expression profile of VIGG was supported by the finding that virus-free meristem cultures prepared from virus-infected grapevines did not express VIGG.

Nested PCR-RFLP is a high-speed method to detect fungicide-resistant Botrytis cinerea at an early growth stage of grapes.

Background: Grey mould caused by the fungus Botrytis cinerea Pers. ex Fr. is one of the major diseases in grapes.

Characterization of a class III chitinase from Vitis vinifera cv. Koshu.

A chitinase gene (Chi3K) was cloned from the genomic DNA of Vitis vinifera cv. Koshu. The structural gene comprised 891 by without introns and encoded 297 amino acids.
